doWriteTo
- Specified by:
doWriteToin classInternalAggregation- Throws:
IOException
-
empty
-
value
public double value()- Specified by:
valuein interfaceNumericMetricsAggregation.SingleValue
-
getValue
public double getValue()Description copied from interface:AvgThe average value. -
getWriteableName
Description copied from interface:NamedWriteableReturns the name of the writeable object- Specified by:
getWriteableNamein interfaceNamedWriteable
-
getLeaderReducer
Description copied from class:InternalAggregationReturn an object that Reduces several aggregations to a single one. This method is called whenInternalAggregation.canLeadReduction()returns true and expects an reducer that produces the right result.- Specified by:
getLeaderReducerin classInternalAggregation
-
finalizeSampling
Description copied from class:InternalAggregationCalled by the parent sampling context. Should only ever be called once as some aggregations scale their internal values- Overrides:
finalizeSamplingin classInternalAggregation- Parameters:
samplingContext- the current sampling context- Returns:
- new aggregation with the sampling context applied, could be the same aggregation instance if nothing needs to be done
-
doXContentBody
public XContentBuilder doXContentBody(XContentBuilder builder, ToXContent.Params params) throws IOException - Specified by:
doXContentBodyin classInternalAggregation- Throws:
IOException
-
